In this paper, we propose and study the distributed blind adaptive algorithms for wireless sensor network applications. Specifically, we derive a distributed forms of the blind least mean square (LMS) and recursive least square (RLS) algorithms based on the constant modulus (CM) criterion. We assume that the inter-sensor communication is single-hop with Hamiltonian cycle to save the power and communication...
In this paper, we present a new structure to implement a switch-beam smart antenna system. The system is able to produce the beam with 6-degree beam-width and steer the beam from 0 to180 degrees in azimuth angle. The proposed system takes the advantage of integrated digital signal processing (DSP) and field programmable gate array (FPGA). In the system, the TI DSP performs digital beamforming and...
In this paper, we proposed an unequal spacing technique which can increase the performance resolution of direction of arrival (DOA) estimation algorithms. The linear prediction (LP) algorithm has been tested for the proposed antenna arrangement, dramatic improvement has been obtained. In addition, we investigate the effect of reference element position on the performance resolution of the LP algorithm...
Future generation of mobile communication system must be capable of serving high quality and broadband services even in highly dense populated area. The radio-over-fibre is one of the promising systems which can be used along the emerging wireless technologies such as smart antenna or multiple input multiple output (MIMO) systems to meet these requirements. In this paper, the role of ROF technology...
